Are you certain you're connected to a USB 3.0 port / with a USB 3.0
cable? (the maximum practical sample rate for USB 2.0 is around 3.75
MHz assuming complex float samples). Do you also see the same problems
if you run benchmark_rate from UHD examples?

Hi sp,
Where did you figure out that gnuradio is little endian?
I searched their source code. In a few places like pmt_serialize.h
they use big endian.
In wavfile.cc they use different code for big or little endian.

So they go as:
int16 data = htobe16(le32toh(int32 data))
Or the associate functions,
htonl, htons
So you need to already have converted your floats to ints...
If in doubt, test them first on a single data..

So they go as:
int16 data = htobe16(le32toh(int32 data))
Or the associate functions,

Sorry about the confusion.

On Sat,
Hi,
I don't know about gnuradio classes:( Maybe you should ask them...
But in C, I would use le32toh, I assume gnuradio is in little endian.
and then htobe16 to get for uhd:
uint16 data = htobe16(le32toh(float 32 data))
I assume this already does ceil or floor, so your data needs to be
already in
I know that data in USRP on FPGA is in format big-endian sint16, but in
Gnuradio data is in format complex float 32...
I found these links
The conversion encompasses several elements. The most obvious is that of
the data type: Most FPGAs use integer data types, the most common being
complex 16-bit
